ACF Repeater field not outputting anything

I'm trying to create multiple image galleries using the Repeater plugin. So I started off with creating a field group called 'Galleries.' Then, the first field I created was also called 'galleries' and the field type was set to Repeater. Inside that field, I created two subfields for 'title and 'image.'

The code below doesn't output anything. Is there something wrong with it?

<?php if( have_rows('galleries') ): ?>

    <ul>

    <?php while ( have_rows('galleries') ) : the_row(); ?>

        <li><?php the_sub_field('title'); ?></li>

    <?php endwhile;?>

    </ul>

<?php endif; ?>
